Energy Transfer and Temperature

What does temperature measure?

• The average kinetic energy of an object's particles

• The amount of heat required to raise the temperature of 1g of a substance by 1 degree Celsius

• The ability of an object to transfer heat

• The total energy of an object's particles

What is thermal energy?

• The energy required to change the temperature of an object

• The average kinetic energy of an object's particles

• The measure of the total energy of motion in an object's particles

• The energy transferred from one object to another

Why does water take a long time to change its temperature?

• Because it has a low specific heat

• Because it is a poor conductor of heat

• Because it is a good insulator

• Because it has a high specific heat

Can two objects have the same temperature but different amounts of thermal energy?

• Yes, if one is more massive than the other

• No, because temperature and thermal energy are the same

• No, unless they are in different environments

• Yes, if they are made of different materials

How do you convert °C to K?

• Subtract 273 from °C

• Multiply °C by 273

• Add 273 to °C

• Divide °C by 273

What is the specific heat?

• The total energy required to raise the temperature of an object

• The ability of a material to transfer heat

• The average kinetic energy of a substance's particles

• The amount of heat required to raise the temperature of 1g of a substance by 1 degree Celsius

Why might a person with a high temperature take a lukewarm bath?

• To increase their body temperature further

• To transfer some of the body's heat to the water

• To measure the body's temperature accurately

• To absorb more heat into the body
